It's been more than three years since [artist id="988"]Green Day[/artist] hit the road, and they're making up for lost time.

On Monday (April 20), they announced the first dates of a massive world tour in support of their upcoming album [article id="1604950"]21st Century Breakdown[/article] (due May 15), a two-month jaunt that will take the band across the U.S. and Canada.

The tour kicks off July 3 in Seattle and wraps August 25 in Los Angeles. No venues have been announced yet, nor have on-sale dates or opening acts.

Green Day's last tour -- in support of their massive American Idiot album -- spanned two years and was their most successful (and lengthy) jaunt to date. While working on Breakdown, the band took time off for a week-long tour as alter egos the [article id="1585150"]Foxboro Hot Tubs[/article].

With Monday's announcement of a tour, it's shaping up to be quite a week for Green Day fans. On Friday at 8 p.m. ET, their much-anticipated new video for the song "Know Your Enemy" will make its world premiere on more than 250 MTV on-air and online outlets.
